Thought:

Suppose someone has refractory problems leading to far sightedness. They can read something if it is of a certain size and distance.

The question is, is it absolute distance from the letters, or is it relative distance?

For instance, would a person with short sightedness, who couldn't read something directly in front of them from 6 feet away be able to read it if they had a mirror reflecting the letters that are 6 feet away at a 45 degree angle next to them? It should mean that if it is a problem with focusing or light gathering, the information is coming from 1 foot away now instead of 6 feet.

Is it possible to use this as a test to determine whether eyesight problems are psychosomatically created?

>They took a vision test while “flying” the simulator. A control group took the same vision test in the cockpit while the simulator was inactive. People’s vision improved only if they were in the working simulator.

>To rule out the possible effect of motivation, the researchers brought another group of people into the cockpit and asked them to read a brief essay on motivation. After people finished reading, they were strongly urged to be as motivated as possible and try hard to perform well in the vision test. The test was conducted while the simulator was inactive. They did not show a significant improvement.

>In an eye exam, we are used to start experiencing problems at the bottom third of the eye chart, where letters start to get small. In another experiment, Ellen Langer and colleagues showed people a shifted chart. At the top, it included letters equivalent to the medium-size letters on the normal eye chart and the chart progressed to letters of very small size at the bottom. Because people were expecting to read the top two thirds of the shifted chart as well, they were able to read much smaller letters.
